DU'lViB-WAITER GUIDE.

To all whom 2'25 may concern Be it known that 1, WILLIAM FnANoIs KING, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Dumb-Waiter Guide, of which the following is a full, clear, and eX- act description.

This invention relates to dumb-waiters or hand power elevators, and has particular reference to the guiding means for such hoisting devices.

Among the objects aimed at is to provide a dumb-waiter guide made entirely of metal so as to comply with the requirements of the municipal ordinances relative to the exclusion of wood or other combustible materials from elevator or dumb-waiter shafts.

Another object is to provide means for anchoring the guides to the wall or walls whereby the guides may be easily adjusted so as to make them adapted for different constructions of elevator cars, and also to make them easier of installation than those now commonly in use.

The above and other objects are attained by means of the mechanism hereinafter fully described and claimed and illustrated in the accompanying drawings, in which Figure 1 is a plan view of one form of my device, a portion of the anchor being broken away, and the guides being in cross section; Fig. 2 is a fragmentary elevation of a pair of guide rails shown connected to one of the anchors; and Figs. 3, a and 5 show different specific forms of the anchors which I may employ in connection with this improvement.

Referring particularly to the drawings, the numeral 10 indicates a conventional form of dumb-waiter, and 11 indicates a counterweight cooperating therewith in the usual manner, both the dumb-waiter and the counterweight being guided in the dumb-waiter shaft 12 for vertical reciprocation.

In Fig. 1 an anchor 13 is shown in the form I prefer to use in connection with a. brick wall in the course of construction. Said anchor is provided with a web 14 tending laterally from the rear face of the anchor plate and provided with an opening or slot is which will receive a portion of the mortar used in the wall construction, whereby the anchor will be the more securely held in place. Furthermore, the rear edge Specification of Letters Patent.

of the web 14 is longer than the front part of the same so as to provide angular portions 14L having interlocking engagement with the finished wall.

On the front face of the anchor plate and extending laterally therefrom into the shaft 12 are attachment lugs 15, each of said lugs being provided with one or more slot-s 15, said slots extending through the lugs from side to side and also reaching from near the outer ends thereof rearwardly toward the base plate of the anchor.

The lugs 15 are adapted to receive the guide rails 16, shown as being provided with flanges 16 adapted to lie against the opposite sides of each lug 15 and there securely clamped in position by means of bolts 17 operating through the slots 15 By reason of the length of the slots, the guide rails may be adjusted. toward or from the wall, for the purposes above indicated. The flanges 16" of the rails extending away from the lugs 15 are adapted to cooperate directly with the guide rollers 10* and 11 of the aforesaid movable parts of the structure.

The anchors 13 may be spaced vertically as far as the builder may find necessary, and since the guide rails 16 are of considerably greater length than the spaces between said anchors, by providing the lugs 15 each with a plurality of slots, it is desirable to connect adjacent rails as indicated in Fig. 2, one end of one rail being connected in the lower slot and the next adjacent rail above being connected in the upper slot of said lug. A companion rail may be connected on the same lug at intermediate portions so as to break joints as indicated in Fig. 2, or all four ends may be connected, if necessary, to the same lug, the adjustment means providing that the rails may be suitably positioned in any event.

The form of anchor 18 shown in Fig. 3 is designed for use in connection with walls made of building blocks during the process of construction of the wall, and differs from the anchor shown in Fig. 1 by the addition of a vertical auxiliary anchor plate 14 connected to the rear edge of the Web extending into the wall. This web, as before, is preferably provided with the open ing 14 and the interlocking extensions 14;. In Fig. 4: the anchor 13 is designed to be applied to existing walls of masonry, the securing means for this form of the anchor being the provision of a slot 14: along the plate of the anchor and through which any suitable form of expansion bolt-s (not shown) may pass to secure the anchor to the wall. The lugs 15 in these two forms correspond to those of Fig. 1 with respect to the arrangement of the slots 15*.

The form of the anchor shown in Fig. 5 is one in which a pair of lugs 15 are shown extending from the anchor plate in close spaced relation and adapted to receive adjustably therebetween the attachment flange ofa single rail having oppositely extending flanges to receive the rollers 10 and 11 The parts of this invention may be made of any suitable metals, and by reason of the easy adjustability of the guide rails on the anchoring means, it is expedient to use anchors of cast metal and without being dressed-or machined for the purpose of securing pro-per operation of the dumb waiter. Such anchors, therefore, are preferably made as unitary castings, the lugs being integral with the plate in each form of the invent-ion.

Having thus described my invention, what I claim as new and desire to secure by Letters Patentis:

1. In a dumb-waiter, the combination with a car and its counterweight, of'a plurality of-guide rails cooperating with said car and counterweight, and anchoring means for said rails, said anchoring means including a plate, means to secure the plate in position, and a plurality of lugs integral with the plate and extending outwardly therefrom toward the car, each lug having one or more slots, for the purpose indicated.

2. An anchor for a dumb-waiter guide comprising a plate, a web extending rearwardly from the plate and provided with means for interlocking cooperation with the wall, and a plurality of integral lugs extending outwardly from the plate in a direction opposite to said web, each lug having a plurality of vertically spaced slots, for the purpose set forth.

8. An anchor for a dumb-waiter guide comprising a plate, a web extending rearwardly therefrom, said web having a central opening and end extensions to interlock with the material of the wall, and a pair of lugs extending outwardly from the plate, said lugs having slots, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM FRANCIS KING.
